N surround

1. A method comprising:

monitoring a calibration tone in a proximity to each of a listener's ears, the calibration tone being calibration sound waves emitted by two or more far-field speakers;

outputting one or more audio portions from two or more near-field speakers based on results of monitoring the calibration tone, the one or more audio portions canceling or reducing at least one of multi-channel cross talk and sound reflections from the two or more far-field speakers.

2. The method of claim 1 , wherein the far-field speakers and the near-field speakers are controlled by a common audio processor.

3. The method of claim 1 , wherein the far-field speakers are controlled by a far-field audio processor, wherein the near-field speakers are controlled by a near-field audio processor.

4. The method of claim 3 , further comprising synchronizing the near-field audio processor with the far-field audio processor.

5. The method of claim 1 , further comprising applying a signal processing algorithm to generate a surround ring that is separate from another surround-sound ring generated by the far-field speakers.

6. The method of claim 5 , wherein the signal processing algorithm is part of an application downloaded to a device in the listener's proximity.

7. The method of claim 1 , wherein the monitoring is in part performed by two or more microphones mounted in the listener's proximity.

8. The method of claim 7 , wherein the microphones are mounted on a pair of glasses worn by the listener.

9. The method of claim 1 , further comprising determining, based on the monitoring, one or more audio properties of far-field sound waves from the far-field speakers as perceived by the listener.

10. The method of claim 9 , wherein the one or more audio properties comprise at least one of inter-aural level difference, inter-aural intensity difference, inter-aural time difference, or inter-aural phase difference.

11. The method of claim 1 , further comprising determining, based on the monitoring, multi-channel cross talk and sound reflections related to far-field sound waves.

12. The method of claim 11 , further comprising canceling or reducing at least one of multi-channel cross talk and sound reflections by outputting near-field sound waves obtained by inverting sound waves in the far-field sound waves.

13. The method of claim 1 , wherein the calibration tone comprises sound waves at high sound wave frequencies beyond human hearing.

14. The method of claim 1 , wherein the calibration tone comprises a plurality of pulses emitted by different ones of the far-end speakers at a plurality of different specific times.

15. The method of claim 1 , wherein the near-field sound waves comprise at least one, two, or more audio cues indicating at least one distance of a sound source other than the far-field speakers, and wherein none of the at least one, two, or more audio cues are detectable from the far-field sound waves.

16. The method of claim 1 , wherein the near-field sound waves comprise at least one, two or more audio cues generated with one or more audio processing filters and/or delays using a head-related transfer function.

17. The method of claim 1 , further comprising interpolating near-field sound waves with the far-field sound waves to form a surround ring that is different from both a surround ring generated by the near-field speakers and a surround ring generated by the front-field speakers.

18. The method of claim 1 , wherein at least one of the near-field speakers is operatively coupled to a mobile device that comprises an audio processing application to add a 3 dimensional (3D) spatial portion in a sound field perceived by the listener.

19. An audio system comprising:

a near-field audio processor configured to control two or more near-field speakers; and

a far-field audio processor configured to control two or more far-field speakers and to output two or more far-field sound waves;

wherein the near-field audio processor is further configured to perform:

synchronizing with the far-field audio processing system;

monitoring, at each of two or more spatial locations adjacent to a listener, two or more calibration sound waves from the two or more far-field sound waves;

outputting two or more near-field sound waves based at least in part on results of the monitoring.

20. A non-transitory computer readable storage medium, comprising software instructions, which when executed by one or more processors cause performance of the method recited in claim 1 .
